If you have a high-deductible health plan, you have probably run into two similar-sounding accounts: a medical savings account (MSA) and a health savings account (HSA). They both let you set aside pre-tax money for medical costs, but the differences in the medical savings account vs HSA matchup can decide which one you can even open.
The short version is that the HSA has largely replaced the older MSA for most people. Still, MSAs exist in specific situations, so it helps to know how each one works before you choose.
Medical Savings Account vs HSA: Quick Comparison
Here is a side-by-side look at the three main account types as of 2026. "MSA" usually refers to an Archer MSA, though Medicare MSAs are a separate program.
| Feature | HSA | Archer MSA | Medicare MSA |
|---|---|---|---|
| Who can open one | Anyone with a qualifying HDHP | Self-employed or small-employer (50 or fewer) workers, mostly closed to new enrollees | Medicare beneficiaries in an MSA plan |
| Who contributes | You and your employer | You or your employer in a given year, not both | Medicare funds it; you cannot add money |
| 2026 contribution limit | $4,400 self-only, $8,750 family | 65% of the deductible (self), 75% (family) | Set by Medicare, varies by plan |
| Tax on qualified withdrawals | Tax-free | Tax-free | Tax-free |
| Rolls over yearly | Yes | Yes | Yes |
| Portable if you change jobs | Yes | Yes | Tied to the Medicare plan |
| Can invest the balance | Yes, at most custodians | Limited | No |
What a Medical Savings Account Is
A medical savings account, specifically an Archer MSA, was an early version of the tax-advantaged health account created in the 1990s. It was aimed at self-employed people and workers at small companies with 50 or fewer employees.
Archer MSAs are mostly closed to new enrollees today. In general, you can only have one if you already had an Archer MSA or work for a small employer that offered them before the program was phased out for new participants.
There is also the Medicare MSA, a different animal. It pairs a high-deductible Medicare Advantage plan with a savings account that Medicare funds for you.
What an HSA Is
A health savings account is the modern, widely available option. Anyone enrolled in a qualifying high-deductible health plan (HDHP) can open one, and both you and your employer can contribute.
For 2026, the IRS set the HSA contribution limits at $4,400 for self-only coverage and $8,750 for family coverage, with an extra $1,000 catch-up contribution allowed at age 55 and older. To qualify, your 2026 HDHP needs a minimum deductible of $1,700 for self-only or $3,400 for family coverage.
HSAs are known for a triple tax advantage. Contributions are pre-tax, growth is tax-free, and withdrawals for qualified medical expenses are tax-free too.
Contribution Limits and Who Pays In
This is one of the clearest differences in the medical savings account vs HSA question. With an HSA, both you and your employer can contribute in the same year, up to the combined annual limit.
With an Archer MSA, only one party contributes in a given year. Either you fund it or your employer does, not both, and the limit is tied to a percentage of your plan's deductible rather than a flat dollar amount.
A Medicare MSA flips the model entirely. Medicare deposits money into your account, and you are not allowed to add your own funds.
Portability and Investing
HSAs are fully portable. The account is yours, it stays with you when you change jobs or health plans, and the balance rolls over year after year with no "use it or lose it" rule.
Most HSA custodians also let you invest the balance in mutual funds or similar options once you hit a minimum, which turns the account into a long-term savings vehicle. Archer MSAs offer more limited investment choices, and Medicare MSAs generally do not allow investing at all.
Which One Fits You?
For most working-age people with an HDHP, the HSA is the practical choice. It is easy to open, has higher and clearer limits, allows employer contributions, and can double as a retirement-style account thanks to investing.
An Archer MSA only makes sense if you already have one or fall into the narrow small-employer group that still offers them. A Medicare MSA is worth reviewing if you are on Medicare and considering an MSA-style Medicare Advantage plan.
Managing the Cash Side of Your Health Account
Your HSA itself must sit with an approved custodian like Lively, but the money you use for premiums, copays, and everyday costs still flows through regular bank accounts. Keeping that cash organized makes it easier to budget for the deductible you have to meet.
An app-based account like Current Banking can help you set aside money for out-of-pocket medical costs with automatic transfers, though it is not an HSA or MSA. It is a simple way to keep your health-spending cash separate from your everyday budget.

Frequently Asked Questions
Is a medical savings account the same as an HSA?
No. A medical savings account (Archer MSA) is an older account with tighter eligibility and lower contribution limits, and it is mostly closed to new enrollees. An HSA is the modern, widely available version that anyone with a qualifying high-deductible plan can open.
Can I still open an Archer MSA in 2026?
Generally no. Archer MSAs were phased out for most new participants, so you typically can only keep one if you already had it or work for a small employer that still offers it. Most people should look at an HSA instead.
What are the 2026 HSA contribution limits?
For 2026, you can contribute up to $4,400 for self-only coverage and $8,750 for family coverage. If you are 55 or older, you can add a $1,000 catch-up contribution on top of those limits.
Do MSA and HSA funds expire at the end of the year?
No. Both Archer MSAs and HSAs roll unused balances over year after year, so there is no "use it or lose it" deadline. That rollover feature is one reason both accounts can build up over time.
